In its design some Byzantine and modern elements are mixed. It has triple arches on its doors and the sky is represented on its ceiling. One of its most characteristic features is that the stars are mimicked with lights behind its altar. In addition, its peculiar design symbolises the Christian spirituality; for example, its grey walls symbolise the human inability to reflect God’s light, and its twelve towers symbolise the twelve apostles and the twelve gates of the Heavenly Jerusalem. It also has a risen Christ statue instead of a crucified Christ one as the rest of cathedrals and churches have.

The Inmaculada Concepción Cathedral is one of the main shrines in the Dominican Republic and one of the largest cathedrals, since it can seat 1,000 attendees. Since it was built, it has been and it is still being one of the most important religious destinations for both domestic and foreign pilgrims.
